The two composers who defined British cinema also wrote inspired operas

It’s my new lockdown ritual. Switch on the telly, cue up the menu and scroll down to where the vintage movies gather — Film 4, or the excellent Talking Pictures TV. Then search through their early-hours offerings, and press ‘record’ more or less at random. Gainsborough costume flicks; Rattigan adaptations; anything with John Mills in a submarine — it’s all good. Then, next day, trawl through the catch to see what’s surfaced, and who wrote the music. On a good night you might get Vaughan Williams in 49th Parallel, Richard Rodney Bennett in Billy Liar or — bewilderingly — the fire-breathing serialist Elisabeth Lutyens, keeping herself in cigarettes and brandy with scores for The Skull or Dr Terror’s House of Horror. It’s all there in black and white: an alternative history of British music, piped straight to your sofa.

What that history might have looked like if postwar theatre had paid as well as cinema — and, in honesty, if Britten and Tippett hadn’t been quite so good — is suggested by two recent opera recordings.
